簡介
一 、 推薦先訪問官網
之前部署openstack一直都是分組件,寫腳本,單獨執行,費時費力,還容易出現異常,現在嘗試了一下使用自動化工具部署openstack,覺得至少部署的速度飆升。希望感興趣的可以嘗試嘗試,這裏僅僅爲了實驗方便,就採用(all-in-one)模式。
① 這個是kolla-ansible的官方網站
https://docs.openstack.org/kolla-ansible/latest/user/quickstart.html
② 這個是ansible的官方網站。
http://docs.ansible.com/
③ 這個是docker的官方網站。
http://docs.ansible.com/
④ 我之前也做了docker的基礎實驗:

二 、環境準備
主機名 | IP | 網卡 |
---|---|---|
opensatck | 172.31.132.253 | eth0 |
第二塊網卡 | eth1 | |
CentOS | 7.5 | |
OpenStack | stein |
[root@openstack ~]# hostnamectl set-hostname --static openstack
[root@openstack ~]# cat /etc/hosts
127.0.0.1 localhost
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.31.132.253 openstack
關閉防火牆,關閉selinux.
三 、 Install packages
1 、 安裝依賴
[root@openstack ~]# rm -rfv * /etc/yum.repos.d/*
[root@openstack ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@openstack ~]# yum install epel-release
[root@openstack ~]# yum install python-devel libffi-devel gcc openssl-devel libselinux-python -y
2 、 安裝 pip,ansible,docker
[root@openstack ~]# yum install python-pip ansible –y
[root@openstack ~]# pip install -U pip
① 安裝 docker-ce
step 1: 安裝必要的一些系統工具
# step 1: 安裝必要的一些系統工具
[root@openstack ~]# sudo yum install -y yum-utils device-mapper-persistent-data lvm2
# Step 2: 添加軟件源信息
[root@openstack ~]# sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# Step 3: 更新並安裝Docker-CE
[root@openstack ~]# sudo yum makecache fast
[root@openstack ~]# sudo yum -y install docker-ce
# Step 4: 開啓Docker服務
[root@openstack ~]# systemctl enable docker;systemctl restart docker
3. 配置 docker 鏡像加速
[root@openstack ~]# mkdir -p /etc/docker
[root@openstack ~]# tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://registry.docker-cn.com"]
}
EOF
[root@openstack ~]# systemctl daemon-reload
[root@openstack ~]# systemctl restart docker
4. 安裝 kolla-ansible(version==8.0.0)
pip install kolla-ansible==8.0.0 #這裏版本嚴格使用8.0.0,否則會報異常錯誤
可以適當添加源
https://mirrors.tuna.tsinghua.edu.cn/pypi/web/simple/
例如:
pip install kolla-ansible==8.0.0 -i https://mirrors.tuna.tsinghua.edu.cn/pypi/web/simple/
如果安裝過程出現報錯,可以先忽略該模塊,如果需要就在安裝。
例如:
Cannot uninstall 'PyYAML'. It is a distutils installed project
and thus we cannot accurately determine which files
belong to it which would lead to only a partial uninstall
則可以先忽略:
pip install kolla-ansible --ignore-installed PyYAML -i https://mirrors.tuna.tsinghua.edu.cn/pypi/web/simple/
需要就在安裝:
pip install XXXX==8.0.0
5. copy文件
[root@openstack ~]# mkdir -p /etc/kolla
[root@openstack ~]# chown $USER:$USER /etc/kolla
[root@openstack ~]# cp -r /usr/share/kolla-ansible/etc_examples/kolla/* /etc/kolla/ ##Copy globals.yml and passwords.yml
[root@openstack ~]# cp /usr/share/kolla-ansible/ansible/inventory/* . ##Copy all-in-one and multinode inventory files
四 、 Prepare initial configuration
1. Configure Ansible /etc/ansible/ansible.cfg
[defaults]
host_key_checking=False
pipelining=True
forks=100
2. 配置主機清單文件,根據部署場景,這裏選擇 all-in-one 文件
[root@openstack ~]# vi all-in-one
# These initial groups are the only groups required to be modified. The
# additional groups are for more control of the environment.
[control]
localhost ansible_connection=local
[network]
localhost ansible_connection=local
[compute]
localhost ansible_connection=local
[storage]
localhost ansible_connection=local
[monitoring]
localhost ansible_connection=local
[deployment]
localhost ansible_connection=local
………………
下面不需要動
3 . 配置 ssh 無密鑰登錄,授權節點
[root@openstack ~]# ssh-keygen
[root@openstack ~]# ssh-copy-id root@openstack
檢查主機連接
[root@openstack ~]# ansible -i all-in-one all -m ping
localhost | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
},
"changed": false,
"ping": "pong"
}
4. 對 /etc/kolla/passwords.yml 文件生成隨機密碼,或者修改爲自定義密碼
[root@openstack ~]# kolla-genpwd
[root@openstack ~]#vim /etc/kolla/passwords.yml
keystone_admin_password: 1111111
5. 配置 /etc/kolla/globals.yml 文件
kolla_base_distro: "centos"
kolla_install_type: "source"
openstack_release: "stein"
kolla_internal_vip_address: "172.31.132.247"
network_interface: "eth0"
neutron_external_interface: "eth1"
nova_compute_virt_type: "qemu"
keepalived_virtual_router_id: "7"
五 、 Deployment
[root@openstack ~]# kolla-ansible bootstrap-servers ##Bootstrap servers依賴
[root@openstack ~]# kolla-ansible prechecks ##檢查配置
[root@openstack ~]# kolla-ansible pull ##pull鏡像
[root@openstack ~]# kolla-ansible deploy ##部署
如果部署出錯:
[root@openstack ~]# kolla-ansible destroy ./all-in-one --yes-i-really-really-mean-it
六 、 Using OpenStack
1.安裝CLI客戶端
pip install python-openstackclient
2.生成環境腳本
kolla-ansible post-deploy . /etc/kolla/admin-openrc.sh
